904L has high nickel composition with low carbon content, copper
alloy adding improve its resistance to corrosion, the “L” in 904L
stands for low carbon, it is typical Super Austenitic stainless
steel, equivalent grades are DIN 1.4539 and UNS N08904, 904L has
better properties than other austenitic stainless steels.

904L Stainless Steel Properties
Excellent resistance to stress corrosion cracking due to the
presence of high amounts of nickel content.
Pitting and crevice corrosion, intergranular corrosion resistance.
Grade 904L is less resistant to nitric acid.
Excellent formability, toughness and weldability, due to low carbon
composition, it can be welded using any standard method, 904L
cannot be hardened by heat treatment.
Non-magnetic, 904L is an Austenitic stainless steel, therefor 904L
possesses Austenitic structure properties.
Heat Resistance, Grade 904L stainless steels offer good oxidation
resistance. However, the structural stability of this grade
collapses at high temperatures, particularly above 400°C.
Heat Treatment, Grade 904L stainless steels can be solution
heat-treated at 1090 to 1175°C, following by rapid cooling. Thermal
treatment is suitable for hardening these grades.
